1. A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions at a treatment range defined between under heating tissue to fail to achieve a therapeutic affect and overheating tissue to cause tissue ablation, the system comprising a controller including a connector to which a first treatment device having a plurality of electrodes for applying radiofrequency energy to tissue is coupled for use, and a generator for applying radiofrequency energy to the electrodes, the improvement comprising a multiple error checking system which if an error is detected which indicates disabling of an electrode of the plurality of electrodes of the treatment device, the system is configured to check for a repeat of the error and configured to determine if disabling is warranted or energy application is warranted to thereby reduce the likelihood of undertreatment of tissue, and further having temperature sensors associated with the plurality of electrodes and an automatic pump system configured to increase the flow of cooling fluid if measured temperature exceeds a predetermined value to maintain tissue temperature below a tissue ablation threshold.
